Former New York Times reporter David Cay Johnston has forged a nice little late-in-life career as one of America's most vitriolic Trump haters. He's written a Trump-hating book, It’s Even Worse Than You Think, and he regularly pops up on MSNBC whenever a dose of anti-Trump venom is desired.

Appearing on today's AM Joy, Johnston reached back in history to slur the President, claiming that his grandfather, Friedrich Trump, built the first Trump fortune by "running whorehouses."

Claim - Gwenda - Blair - Biography - Trump

That is a claim that is unverified at best. Gwenda Blair wrote the most definitive biography of the Trump family. And as per this Washington Post article, Blair "was careful not to say that Trump ran brothels. I think we don’t quite know that.”

In 2015, the liberals at Snopes.com addressed the question: "Did Donald Trump’s Grandfather Make His Fortune in Prostitution?" Snopes ruled: "Mostly False."

Note - Johnston - Whorehouse - Claim - Description

Note: Johnston prefaced his "whorehouse" claim by trotting out the lurid description of President Trump as "the head of a white-collar crime family," one who "spent his entire life as the third-generation head of a criminal organization."

Note segundo: Reid completely mischaracterized a statement Trump reportedly made to Director of National Intelligence Dan Coats. She has Trump complaining to Coats that because of the investigation into him, "I can't do anything with Russia. There's things I'd like to do with Russia: with trade, with ISIS, and they're all over me with this."
